A black hole is created when a large star burns out. Like our sun, stars are unbelievably hot furnaces (熔爐) that burn their own matter as fuel. When most of the fuel is used up, the star begins to die.
The death of a star is not a quiet event. First there is a huge explosion. As its outer layer is blasted off into space, the dying star shines as brightly as a billion suns.
After the explosion gravity pulls in what’s left of the star. As the outside of the star sinks toward the center, the star gets smaller and smaller. The material the star is made of becomes tightly packed together. A star is so dense that a teaspoon of matter from it weighs billion of pounds.
The more the star shrinks, the stronger the gravity inside it becomes. Soon the star is very tiny, and the gravity pulling it in is unbelievably strong. In fact, the gravity is so strong that it even pulls light into the star! Since all the light is pulled in, none can go out. The star becomes black when there is no light. Then a black hole is born!
That’s what we know about black holes. What we don’t know is this: What happens inside a black hole after the star has been squeezed into a tiny ball? Does it keep getting smaller and smaller forever? Such a possibility is hard to imagine.
But if the black hole doesn’t keep shrinking, what happens to it? Some scientists think black holes are like doorways to another world. They say that as the star disappears from our universe, it goes into another universe. In other words a black hole in our universe could turn into a “white hole” in a different universe. As the black hole swallows light, the white hole shines brightly—somewhere else. But where? A different place, perhaps, or a different time — many years in the past or future.
Could you travel through a black hole? Right now, no. Nothing we know of could go into a black hole without being crushed. So far the time being, black hole must remain a mystery.
Black holes are a mystery—but that hasn’t stopped scientists from dreaming about them. One scientist suggested that in the future we might make use of the power of black holes. They would supply all of Earth’s energy needs, with plenty to spare. Another scientist wondered if a black hole could some day be used to swallow earthly waste—a sort of huge waste disposal(處理) in the sky!

American’s genius with high technology may have put men on the moon, but there is growing doubt about its ability to solve human problems closer to home.
In fact, a slight but significant change from purely technological solutions is already under way as scientists insist that answers to the world’s problems will not come from an attractive exhibition of electronics and machines. Instead, as they see it, solutions must develop from a better understanding of the humans that drive the system and from a fuller appreciation of the limits and potential(潛能) of the earth’s resources.
What this means is an increased emphasis on the life and earth sciences, on sociology, psychology, economics and even philosophy.
More and more of the best minds in science, particularly young researchers, are being drawn into these developing fields.
All this is not to say that technological creativity will not play a critical role in solving energy and food shortages, or that answers to environmental difficulties will not come from further advances in the same technologies that may have helped cause the problems.
Where the real challenge lies, in the view of the new generation of scientists, is in finding ways to produce goods and meet the world’s needs, using less of the raw materials that are becoming short.
小題1:Which of the following would the author probably agree with?
A.The environment crisis will not be solved unless we stop using virgin(原始)materials.
B.In scientific research, a higher priority(優(yōu)先)should be given to understanding all living systems.
C.Exploration of outer space will finally lead to an improvement on human living conditions.
D.U. S. high-technology companies are welcoming this new change in scientific research.
小題2:Which of the following best expresses the main idea?
A.a(chǎn) growing number of Americans are doubtful about what high technology can do in solving the world’s problems.
B.Many scientists are beginning to believe that the better understanding of human beings will play a more decisive role in solving the world’s problems.
C.More and more young scientists are trying their best to find new ways to solve the world’s problems.
D.Technological creativity will still play a very important part in solving the world’s problems.
小題3:Young scientists demand that in order to satisfy human needs ________.
A.existing products be improved.
B.more complex machines and electronic equipment be designed.
C.ways be found to produce better goods using fewer raw materials.
D.a(chǎn)ny new invention and innovation be encouraged in technology
小題4:In the passage “Human problems” or “world problems” refers mainly to ______.
A.global food shortageB.resources depletion(耗盡)
C.environmental pollutionD.a(chǎn)ll of the above
小題5:The author states all the following CXCEPT that _______.
A.the development of present techniques cannot provide any answers to today’s problems.
B.a(chǎn)n increasing number of young scientists are taking a great interest in biological and social sciences.
C.many scientists have come to understand the limits of natural resources.
D.many scientists argue that high technology is something but not everything.

Every year 2.2 million tons of oil are spilled ( 散落,濺出 ) into the ocean. Actually, this only amounts to a small percentage of the total 1.6 billion tons of oil shipped around the world each year.However, this spilled oil has terrible effects on ocean life, including the coastlines where the off washes up onto shore. Some of the largest spills in history were caused by oil tankers running into each other or by an oil tanker sailing into shallow water and hitting the bottom of the ocean.
After these spills, officials try to discover who or what was at fault to help prevent similar accidents in the future.
One of the worst oil spills in history occurred along the Alaskan coastline in 1989. In this accident, 42,000 tons of oil spilled from a tanker which resulted in terrible damage to this sensitive natural area. In this spill, the tanker's captain, who was tired from overwork and drinking alcohol, had gone to___________. He gave control of the ship to the third mate. The third mate was unfamiliar with the path the ship took, and he ran the ship onto Blighe Reef. Blighe Reef is a natural underwater rock wall near the Alaskan coast. Damaged by the reef, the ship leaked oil out into the ocean. More than 1,600 kilometers of coastline were affected by the oil spill. Some scientists who studied nature in the area guessed that 580,000 birds and 5,500 otters died when the oil from the spill covered their skin. As well, smaller shellfish and other sea creatures were later eaten by seals, whales, and other animals. The most oil ever spilled was actually dumped on purpose as an act of ecological warfare. The term ecological warfare means to fight by doing harm to nature in the area under attack. In 1990, Iraq sent soldiers into Kuwait and set off the Persian Gulf War. As part of the Iraq war plan,900,000 tons of oil were let out into the Persian Gulf Way Iraq. This oil covered 1,500 square kilometers of water in the Persian Gulf. The oil also damaged 650 kilometers of the coastline of both Kuwait and Saudi Arabia. In some places, oil floating on the water was measured to be 43 centimeters thick. Water birds, water plants, and baby fish were all seriously affected by the oil. The long-term effects of this act on the food chain in the area are bound to cause problems tar into the future.

Happiness and sadness are states of being that define the way we view the world. It is often said that some people by nature have a sunny character. Now scientists may have discovered why.
Some people may be born for happiness, while others are genetically negative, scientists have suggested in a study published late February in a British journal.
Earlier research had already established that the gene known as 5-HTTLPR plays a key role in determining how the neurotransmitter (神經(jīng)傳遞素) serotonin (含于血液中的復(fù)合胺) works within the brain. Serotonin, a hormone (荷爾蒙), passes chemical messages between nerve cells. It has been closely linked to mood. Several anti-depressant (抗抑郁) drugs regulate serotonin levels. Scientists had also identified three variants (變體) of the gene. Two so-called "short" variants were linked to a higher risk of depression and suicide attempts. Unlike the two "short" variants, the "long" variant of 5-HTTLPR showed a clear dislike of negative images, such as fierce animals, and a clear liking for positive ones, such as flowers.
Researchers from the University of Essex in Britain, led by Elaine Fox, showed participants a series of images. The images were divided into three kinds: negative ones aimed at inspiring fear or stress such as a spider or person about to commit suicide, pleasant ones and neutral (中性的) ones. The participants who had the long variant of the 5-HTTLPR gene "showed a clear dislike of negative material alongside a careful attention for positive material," the researchers found. They paid close attention to the pretty pictures, and ignored the frightening ones. On the other hand, the short variant groups had the opposite reaction.
In January, the Australian government organized "happiness workshops", teaching government staff how to be happy. The department that held the "happiness workshops" said unhappy staff weren't productive staff. Australian political opposition parties have argued that the "happiness workshops" are probably a waste of money and couldn't increase productivity as intended. However, whether the workshop will have a happy or disappointing result, we will have to wait and see.
1. For the passage,by what means can we view the world?
A. Happiness and sadness.                                        B. Happiness and curiosity.
C. Sadness and amazement.                                      D. Disappointment and sadness.
2. What is most important in the role of deciding how the the neurotransmitter serotonin works within the brain?
A. The gene known as 5-HTTLPR.                            B. Three variants.
C. Neurotransmitter serotonin       .                                  D. A hormone.
3 Which of the following sentences is WRONG?
A. Serotonin, a hormone within the brain., passes chemical messages between nerve cells, which has been closely linked to mood.                                  
B. Scientists identified the two "short" variants, and the "long" variant of 5-HTTLPR which showed a clear hatred of negative images, such as fierce animals.     
C. Scientists identified three variants of the gene. Two so-called "long" variants were linked to a higher risk of depression and murder attempts.                        
D. In terms of researchers’ research, the images were divided into three kinds: negative ones, pleasant ones and neutral ones.  
4. Why did the Australian government organize “Happiness workshops”?
A. To enrich staff’s free life.                                
B. To teach staff the ways to be happy.
C. To prove the result of the researchers’ research.     
D. To test who weren’t productive staff.
5. What is the result of setting up “Happiness workshops” according to the last paragraph?
A. A waste of money.

While all my classmates seen to be crazy about a one-way ticket to Mars(火星), I’d rather say Mars is totally unsuitable for human existence. People won’t have enough food supplies there, and the terrible environment would make it impossible for them to live a long life. Besides, the journey won’t be safe. Can anybody explain to me just why people would go to Mars, never to return?
Steve Minear, UK
Here are the things you can think of: the desire to explore a foreign and unique environment, the excitement of being the first humans to open up a new world, the expectation of fame and glory…For scientists there is another reason. Their observations and research will probably lead to great scientific achievements.
Donal Trollop, Canada
There are already too many people on the Earth. I think that sometime before the end of the century, there will be a human colony(殖民地)on Mars. It will happen when people finally realize that tow-way trips to the red planet Mars are unnecessary. Most of the danger of space Flight is in the launches(發(fā)射) and landings. Cutting the trip home would therefore reduce the danger of accidents, save a lot of money, and open the way to building an everlasting human settlement on another world.
Enough supplies can be sent on ahead. And every two years more supplies and more people will needs, and Mars is far more pleasant than the other planets in the outer space.
Paul Davies. USA
小題1: The main purpose of Steve Minear’s writing is     .

“It hurts me more than you”, and “This is for your own good” —these are the statements my mother used to make years ago when I had to learn Latin, clean my room, stay home and do homework.
That was before we entered the permissive period in education in which we decided it was all right not to push our children to achieve their best in school. The schools and the educators made it easy for us. They taught that it was all right to be parents who take a let-alone policy. We stopped making our children do homework. We gave them calculators, turned on the television, left the teaching to the teachers and went on vacation.
Now teachers, faced with children who have been developing at their own pace for the past 15 years, are realizing we’ve made a terrible mistake. One such teacher is Sharon Clomps who says of her students—“so passive” —and wonders what has happened. Nothing is demanded of them, she believes. Television, says Clomps, contributes to children’s passivity. “We’re talking about a generation of kids who’ vet never been hurt or hungry. They have learned somebody will always do it for them, instead of saying ‘go and look it up’, you tell them the answer. It takes greater energy to say no to a kid.”
Yes, it does. It takes energy and it takes work. It’s time for parents to end their vacation and come back to work. It’ s time to take the car away, to turn the TV off, to tell them it hurts you more than them but it’ s for their own good. It’s s time to start telling them no again.
小題1:Children are becoming more inactive in study because _______.
A.they watch TV too oftenB.they have done too much homework
C.they have to fulfill too many dutiesD.teachers are too strict with them
小題2:We learn from the passage that the author’s mother used to lay emphasis on _______.
A.learning LatinB.discipline
C.natural developmentD.education at school
小題3: By “permissive period in education” (L.1, Para.2) the author means a time _______.
A.when children are allowed to do what they wish to
B.when everything can be taught at school
C.when every child can be educated
D.when children are permitted to receive education
小題4:The main idea of the passage is that _______.

B.kids should have more activities at school
C.it’s time to be more strict with our kids

Believe it or not, optical illusion(錯覺) can cut highway crashes.
Japan is a case in point. It has reduced automobile crashes on some roads by nearly 75 percent using a simple optical illusion. But stripes, called chevrons(人字形), painted on the roads make drivers think that they are driving faster than they really are, and thus drivers slow down.
Now the American Automobile Association Foundation(基金會) for Traffic Safety in Washington D.C. is planning to repeat Japan’s success. Starting next year, the foundation will paint chevrons and other patterns of stripes on selected roads around the country to test how well the patterns reduce highway crashes.
Excessive (too great) speed plays a major role in as much as one fifth of all fatal traffic accidents, according to the foundation. To help reduce those accidents, the foundation will conduct its tests in areas where speed-related hazards (danger) are the greatest curves, exit slopes, traffic circles, and bridges.
Some studies suggest that straight, horizontal bars painted across roads can initially cut the average speed of drivers in half. However, traffic often returns to full speed within months as drivers become used to seeing the painted bars.
Chevrons, scientists say, not only give drivers the impression that they are driving faster than they really are but also make a lane appear to be narrower. The result is a longer lasting reduction in highway speed and the number of traffic accidents.
小題1:The passage mainly discusses ________.
A.a(chǎn) new way of highway speed control
B.a(chǎn) new pattern for painting highways
C.a(chǎn) new way of training drivers
D.a(chǎn) new type of optical illusion
小題2: On roads painted with chevrons, drivers tend to feel that ________.
A.they should avoid speed-related hazards
B.they are driving in the wrong lane
C.they should slow down their speed
D.they are coming near to the speed limit
小題3: The advantage of chevrons over straight, horizontal bars is that the former ________.
A.can keep drivers awakeB.can cut road accidents in half
C.will look more attractiveD.will have a longer effect on drivers
小題4:The American Automobile Association Foundation for Traffic Safety plans to ________.
A.try out the Japanese method in certain areas
B.change the road signs across the country
C.replace straight, horizontal bars with chevrons
D.repeat the Japanese road patterns
小題5:What does the author say about straight, horizontal bars painted across roads?
A.They are suitable only on broad roads.
B.They are falling out of use in the United States.
C.They are ignored in a long period of time.
D.They cannot be used successfully to traffic circles.

The legal age for drinking alcohol in the United States is twenty-one. Underage drinking is a crime but also a common part of college social life. This week in our Foreign Student Series, we look at alcohol rules at American colleges and universities. These rules differ from school to school, as do measures. But many schools have been moving to strengthen their rules.
The United States has more than 17000,000 students in higher education. Each year, 1700 of them die from alcohol-related road crashes and other injuries. 600,000 more are injured while under the influence of alcohol. And almost 700,000 are attacked by another drunken.
One behavior that college officials are trying to prevent is too much drinking. Some researchers have found that students who think binge drinking is normal often think extremely how much other students really drink. A person can die of alcohol poisoning. At Oklahoma University, a nineteen-year-old student died from drinking heavily at a party in 2005
Now alcohol is banned from all sorority houses and university housing. Student organizations can serve alcohol at events but only on Friday and Saturday nights. Other new requirements include an alcohol education program that first-year students take online.
The rules govern behavior on campus (校園) and off. With a first violation(違犯), students pay seventy-five dollars and their parents are told. They must also take an alcohol education class. For a second "strike," they have to pay one hundred fifty dollars. A third strike means that they have to be suspended school for at least one semester.
Since 2005, 363 students have had a first strike. 30 have had a second strike -- and only one hasn’t allowed to go to school for one semester. The president at Oklahoma tells us the aim is not just to punish but to change behavior and the culture at the university.
小題1:The first paragraph mainly tells us that_________.
A.the legal age at the lowest for drinking alcohol is 21
B.many colleges consider drinking alcohol to be a crime
C.drinking alcohol is a necessary and popular campus culture
D.American colleges and universities have their own alcohol rules
小題2:Every year the number of the students who die or are injured because of alcohol in the USA added up to about _______.
A.17000,000B.1,301,700 C.601,700D.1300,000
小題3:If a student has a third strike, he/she should________.
A.have to stop going to school for a timeB.be removed to another school
C.be locked at home for a period D.be forced to leave school forever
小題4:Which of the following statements is supported by the passage ?
A.College students are not allowed to drink alcohol at any time..
B.If students take an alcohol program online, they can drink alcohol .
C.Students having a first strike only receive punishment of fine
D.Students with a second strike pay twice as much as students with a first strike
小題5:We can infer ________from the last two paragraphs.
A.a(chǎn)lcohol rules have no effect on college students
B.drinking alcohol remains a serious problem
C.a(chǎn)lcohol rules aim to change behavior and the culture at the university.
D.the number of students drinking alcohol is dropping in one way.
